Well Brother Egyptian Philosophy in general was religious in nature. Based off of Maat. The Greeks took it and remixed it the best they could. Nothing wrong with that they at least gave credit to where they learned.
Iamblichus wrote that Thales of Milete had to make it clear to Pythagoras that the latter had to go to Memphis, in Egypt, to study. Thales added that it were the Egyptian priests that were a veritable source of knowledge and information. Thales stated this at a time when he himself was Greeces most famous and applauded philosopher, even though it would be his protégé Pythagoras who is currently best remembered as the first philosopher.
After Socrates death, Plato left for Egypt, where he studied for a period of 13 years. His mentor was Sechnuphis, a priest of Heliopolis (modern Cairo and thus near the Great Pyramid).
Years afterwards, Strabo would travel through Egypt. His Egyptian guide showed him where Plato had lived. It was how Plato learned the fable of Thoth and Amun, which he wrote down in Phaedros.
